Satellite: NOAA-15
Taken yesterday: August 4, 2004; flyover beginning 6:05pm EDT
These images show Hurricane Alex taken from the vantage point of NOAA's 850km-high (530 mile-high) Polar Orbiting satellites.

Looking straight down the eye of the storm: Hurricane Alex southeast of Cape Cod (Massachesetts).
At its widest, the eye of the hurricane is about 45 kilometers across.
Since this was taken in the evening, it is difficult but still possible to see down to the ocean's surface in the calm eye.
The thermal image at the bottom of the page, taken in infrared light, clearly reveals the warmer ocean surface within the eye.
